    The following works just fine in FireFox to set focus to a text box when the form is in edit mode:

    Private Sub grd_ItemDataBound(ByVal sender As ObjectByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grd.ItemDataBound 
    If (TypeOf (e.Item) Is GridEditFormItem) AndAlso e.Item.IsInEditMode Then 
    Dim box As TextBox = e.Item.FindControl("ContactName"
    grd.ClientSettings.ClientEvents.OnRowCreated = String.Format("document.getElementById('{0}').focus()", box.ClientID) 

    In IE I get an error:

    Sys.InvalidOperationException: Handler must be a function.

    function Sys$Component$_setReferences(component, references) { 
     ... other code here ... 
        if (events) { 
            for (var name in events) { 
                if (!(component["add_" + name] instanceof Function)) throw new Error.invalidOperation(String.format(Sys.Res.undefinedEvent, name)); 
                if (!(events[name] instanceof Function)) throw new Error.invalidOperation(Sys.Res.eventHandlerNotFunction); 
                component["add_" + name](events[name]); 

    The var name contains "rowCreated" suggesting that IE doesn't like "document.getElementById('{0}').focus()"

    I have also tried inserting a function call here with a function in the ascx. This works in FF but, yet again not in IE.

    I have read a lot of posts on this subject and tried many without success. IE seems to be the difficulty as it works in FF, Safari and Chrome.

    All I want to do is setfocus to a text box when the grid enters edit mode. Not that I think this should be a problem but I am using dynamically loaded ascx controls running in DotNetNuke.

    Hello Declan ,

    You have 3 options to achieve this functionality:

    1. Enable RadGrid.KeyboardNavigation - thus when item enter in edit mode first editable control in the current EditForm will be focused. You should enable the following settings:
    <ClientSettings AllowKeyboardNavigation="true">  

    2. On RadGrid.ItemDataBound event  use this code:
    void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)  
            if (e.Item is GridEditFormItem && e.Item.IsInEditMode)  
                TextBox control = ((GridTextBoxColumnEditor)((GridEditFormItem)e.Item).EditManager.GetColumnEditor("ShipName")).TextBoxControl;  
    3. If both approaches above doesn't help you can try this one:
        void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)  
            if (e.Item is GridEditFormItem && e.Item.IsInEditMode)  
                TextBox control = ((GridTextBoxColumnEditor)((GridEditFormItem)e.Item).EditManager.GetColumnEditor("ShipName")).TextBoxControl;  
                StringBuilder script = new StringBuilder();  
                script.AppendFormat(@"$get('{0}').focus();", control.ClientID);  
                RadGrid2.ClientSettings.ClientEvents.OnGridCreated = script.ToString();  

    I hope this was helpful.

    try this 


    if (e.Item.OwnerTableView.Name == "gvVendor" && e.Item is GridEditFormItem && e.Item.IsInEditMode)




    TextBox txtVendorName = (TextBox)e.Item.FindControl("txtVendorName");





    else if (e.Item.OwnerTableView.Name == "gvProducts" && e.Item is GridEditFormItem && e.Item.IsInEditMode)




    TextBox txtswName = e.Item.FindControl("txtswName") as TextBox;
